Merge ACPI changes related to device enumeration, device object managenet, operation region handling, table parsing and sysfs interface: - Use ZERO_PAGE(0) instead of empty_zero_page in the ACPI device enumeration code (Giulio Benetti). - Change the return type of the ACPI driver remove callback to void and update its users accordingly (Dawei Li). - Add general support for FFH address space type and implement the low- level part of it for ARM64 (Sudeep Holla). - Fix stale comments in the ACPI tables parsing code and make it print more messages related to MADT (Hanjun Guo, Huacai Chen). - Replace invocations of generic library functions with more kernel- specific counterparts in the ACPI sysfs interface (Christophe JAILLET, Xu Panda). * acpi-scan: ACPI: scan: substitute empty_zero_page with helper ZERO_PAGE(0) * acpi-bus: ACPI: FFH: Silence missing prototype warnings ACPI: make remove callback of ACPI driver void ACPI: bus: Fix the _OSC capability check for FFH OpRegion arm64: Add architecture specific ACPI FFH Opregion callbacks ACPI: Implement a generic FFH Opregion handler * acpi-tables: ACPI: tables: Fix the stale comments for acpi_locate_initial_tables() ACPI: tables: Print CORE_PIC information when MADT is parsed * acpi-sysfs: ACPI: sysfs: use sysfs_emit() to instead of scnprintf() ACPI: sysfs: Use kstrtobool() instead of strtobool()

ACPI: thermal: Adjust critical.flags.valid check

2022-12-07T17:06:00+00:00

It is not necessary to compare critical.flags.valid to 1 in acpi_thermal_trips_update() and doing so is also inconsistent with other similar checks in that code, so simply check if the flag is not 0 instead. No expected functional impact. Signed-off-by: Rafael J. Wysocki

ACPI: make remove callback of ACPI driver void

2022-11-23T18:11:22+00:00

For bus-based driver, device removal is implemented as: 1 device_remove()-> 2 bus->remove()-> 3 driver->remove() Driver core needs no inform from callee(bus driver) about the result of remove callback. In that case, commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned. Now we have the situation that both 1 & 2 of calling chain are void-returned, so it does not make much sense for 3(driver->remove) to return non-void to its caller. So the basic idea behind this change is making remove() callback of any bus-based driver to be void-returned. This change, for itself, is for device drivers based on acpi-bus.

ACPI: thermal: Drop some redundant code

2022-10-05T15:51:52+00:00

Drop some redundant initialization of local variables, a redundant return statement and a redundant "else" from the ACPI thermal driver. No functional impact. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano

ACPI: thermal: Drop redundant parens from expressions

2022-10-05T15:51:52+00:00

Some expressions in the ACPI thermal driver contain redundant parentheses. Drop them. No functional impact. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano

ACPI: thermal: Use white space more consistently

2022-10-05T15:51:52+00:00

The usage of white space in the ACPI thermal driver is not very consistent, so improve that a bit. While at it, add missing braces to if()/else in a few places. No functional impact. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano
